1 answer:
Answer:
2. can dissolve.
Explanation:
Ionic compounds are compound that have a positive charge and a negative charge. The compound have cations and anions. Base on the question sodium chloride is an Ionic compound . The sodium produces the cation ions (Na+) while the chlorine produces the anions (Cl-). Generally, ionic compound has a strong bond.
Stirring sodium chloride in water, Alice is most likely to demonstrate the ability of ionic compound to dissolve in water. Ionic compounds dissolves in polar solvent like water. The opposite charge present in the ionic compound are usually dissociated when they are immersed in water. The cations of sodium are surrounded by the negatively charged oxygen ion while the anions of chlorine are surrounded by the positively charged hydrogen ion. The water molecules surround the ions available in the ionic compound thereby preventing it from recombining. All of the water molecules surround the ions of the ionic compound to dissolve it.
The picture above demonstrate how NaCl is dissolve in water.

Tetrahedral arrangement is resulted upon mixing one s and three p atomic orbitals, resulting in 4 hybridized orbitals →
hybridization.
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.
